采用矫正壁厚再进行径向整形的方法,可使铁基含油轴承同轴度的精度平均由φ0.15mm提高至φ0.07mm。作者并根据实际经验提出了烧坯内外径的矫正—整形余量的计算方法。
The method of correcting the thickness of the wall and then performing radial shaping can increase the accuracy of the coaxiality of the iron-based oil-bearing to be increased from φ0.15mm to φ0.07mm on average. Based on the practical experience, the author proposed the correction of the inner and outer diameter of the sinter - the method of calculating the residual allowance.
